Project: Independent Suspension System for Exploration Vehicle
Advanced engineering for mobility in extreme terrain
The Challenge and Technical Approach
A client specializing in geological research requested the development of a vehicle capable of traversing rocky and uneven terrain with increased stability and comfort for sensitive measurement equipment. The main challenge was designing a suspension system that would provide a large, independent working travel for each wheel, while maintaining the structural rigidity of the chassis.
Our approach was modular. We designed a system with longitudinal swing arms made of alloy steel, incorporating adjustable hydropneumatic elastic elements. We used CFD simulations to analyze load distribution and optimized the geometry of the anchor points to minimize vibration transfer to the cabin. The process involved rapid prototyping of key components and rigorous testing on our in-house test benches.
Implementation and Results
The final solution was integrated onto a reinforced "ladder frame" type chassis. Implementation included mounting hydropneumatic blocks with pressure sensors for dynamic stiffness adjustment, directly from the control cabin. The all-wheel drive transmission was adapted to work in symbiosis with the new suspension, ensuring optimal traction even under conditions of differential wheel engagement.
The results were remarkable: the vehicle achieved 40% better lateral stability in turns on slopes, and cabin-terrain isolation increased by over 60%. The client reported exceptional reliability during 6-month missions in mountainous areas, with no system failures. The project demonstrated that dedicated engineering solutions can radically extend the operational capabilities of utility platforms.
